Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614728, here are decompositions:

31 + 31614697 = 31614728
97 + 31614631 = 31614728
127 + 31614601 = 31614728
181 + 31614547 = 31614728
499 + 31614229 = 31614728
547 + 31614181 = 31614728
619 + 31614109 = 31614728
631 + 31614097 = 31614728

Showing the first eight; more decompositions exist.
